This pad is the second step in the Rupes Big Foot Polishing System. The Green Medium Foam Pad is very dense in its construction and was designed to be used with Rupes Quarz Gloss Medium Gel Compound to remove swirl marks, water spots and other paint imperfections. This pad is aggressive enough for most applications on factory clear coat systems. Always follow this pad with a less aggressive pad/polish combination to maximize gloss and surface smoothness. Quantity of ONE.
